echo '<td><a href="candidates.php?id=' . $row['candidate_id'] . '">Delete Candidate</a></td>';

How can i add a confirmation message before the data will be deleted? Like asking are you sure

  • javascript popup that cancels the action if the user clicks "cancel": `onclick="return confirm('Are you sure?');` – simlev Aug 15 '17 at 06:46

    Or here or in the next confirmation page you should make a POST instead of a GET request. To avoid browsers and search engines auto-deleting your content by accident. – jeroen Aug 15 '17 at 06:47

    You should even be using a form with CSRF token instead of a simple link – smarber Aug 15 '17 at 06:59

Try this 

echo '<td><a href="candidates.php?id=' . $row['candidate_id'] . '" onclick="return confirm('Are you sure...?')">Delete Candidate</a></td>';

    You really shouldn't be using a link in combination with javascript for a delete action. – jeroen Aug 15 '17 at 06:48
  • @jeroen What are the downfalls to this? Personally, I've never used such combination before, as I would handle the confirmation before I make a POST request to manipulate the data. – Zhi Kai Aug 15 '17 at 06:55

    See my comment below the question. And if javascript is disabled, there is no confirmation at all (Opera mini?). – jeroen Aug 15 '17 at 07:23

Use confirm function from javascript

confirm('message');

echo '<td><a href="candidates.php?id=' . $row['candidate_id'] . '" onclick="return confirm('message goes here')">Delete Candidate</a></td>';
